I have half of an SCP done, just the SCPs and the Description, and was hoping to get some feedback before moving on to the Addendums, Incident Reports, etc. Am I in the right place? If so, my sandbox is http://scpsandbox2.wikidot.com/alex-curtis

Moved to Drafts and Critiques, since Ideas and Brainstorming is for getting feedback on concept only—generally, things that aren't in draft form yet. If you're unsure, take a look at what the other threads in the forum look like. If yours doesn't match, then it's not in the right place. ~Zyn

SCP-2790 is to be moved to a circular chamber with a 15 meter radius lined with 3cm plates of stainless steel and a secondary layer under that of meter thick concrete to prevent total transmutation of the interior wall of the chamber.

I'm having trouble visualizing how the walls of the chamber are laid out. Are the floors and walls both lined with concrete and steel? Why is the concrete 33 times thicker than the steel?

Description:

Bold this.

Detailed analysis of composition is impossible as the object responds to attempts at obtaining a sample or any other attempts at causing damage to it with a lethal telepathic force, causing a massive brain aneurysm in the threatening person, regardless of what stage of activation it is in.

How do we know that the aneurysm is caused by a telepathic force? Did we measure that force somehow?

When in an active state, SCP-2790 performs "miracles" (ie. levitation; transmutation of objects to gold, silver, and other precious metals; etc.) through the use of telepathic, telekinetic, and minor reality bending abilities.

Don't use 'words in quotes' like this. That's just unprofessional. Rather than 'miracle', use the phrase 'various anomalous actions'.

When a subject (referred to as "supplicant") starts to worship 2790, it creates a telepathic link with them. It then uses this link to" feed " off them, causing the supplicant to start to exhibit signs of malnourishment.

Again, remove the quotes from 'supplicant'. What exactly is 'feeding'?

It is unknown how SCP-2790 does this, but the effects of this feeding are apparent.

Again, what is the SCP doing? 'The effects of this feeding are apparent' is neither apparent nor clinical.

Additionally, SCP-2790 is capable of passing along some of its telepathic powers to its followers changing the physiology of its followers, allowing them to influence others, making it easier for them to find new supplicants to expose to the statue's influence. (For more information on SCP-2790-1, see Addendum 2)

Followers or supplicants? Pick a term and stick with it.
Move the period to after the parentheses.

After gathering 1█ to 2█ supplicants,

This blackbox serves no purpose at all. What it's telling me is that between 10 and 29 supplicants will do the trick. That's barely removing any information at all.

After two hours, they stand and say in a monotone voice "As you command, so shall it be".

"The subject" instead of 'they'.

This is the stage where the object starts communicating with its followers telepathically as well, reassuring them of the divinity of the statue and strengthening its grip on their minds. Its "miracles" become bigger in scale at this stage, instantly transmuting large continuous sections of an object into different forms, flying around the room, and fine manipulation of objects within ten meters of itself.

This is a hugely nonclinical paragraph, from 'reassuring them of the divinity of the statue' to 'strengthening its grip on their minds' to 'Its "miracles" become bigger in scale'.

SCP-2790 starts emitting a bright light that almost instantly converts anyone exposed into an SCP-2790-1 instance and strengthens the link between them and the SCP.

Isn't everyone around the SCP at this point going to be an instance?

Over the course of the next three hours, it drains all of the life force out of them, and the statue then falls into a dormant state.

Aside from that, the compulsion aspect of the statue strips it of a huge amount of potential story and characterization. It becomes a statue that turns people into… vampires or something (that's not elucidated upon this state) for the sake of turning other people into vampires and then draining them? SCP-370 has a very similar concept, but takes it in a much creeper, more thrilling direction.

Thank you for your input, this is very far from a final product, I just wanted to get the idea out there and see what people thought. I think my problem at the moment is I have a picture of exactly what I want the SCP to do, it's just getting used to conveying it in the style. Thank you for your notes, I will see what I can do with it later

I recommend getting the base idea polished up in the Ideas and Brainstorming forum before you try fixing the draft. Go to that forum, post a quick summary of the concept you want to write up (don't link the draft unless someone asks), and reviewers there can help you make the idea more interesting and give you some advice on structuring the eventual article for smoothness of reading and narrative.
